Abstract

Urbanization, land surface temperatures and pollution cause to make major change in urban environment which such implications are evolution Geomorphic Systems. Weathering is the most important process in Geomorphic Systems that altere in metropolis. Tehran is the largest and the most important city in Iran, due to enlargement, high population and high level of airpollution density, the Geomorphic System has been changed. The meteorological data (1990-2009) of stations in Tehran and Pollution data (2009-2011) including SO2 and NO2 of 15 stations and high gain thermal infrared image of Landsat ETM+ in 11 April 2001 were used. Physical Weathering was studied in thermal expansion and Freeze-thaw classes. Zonation of the Weathering of the primary elements was performed by kriging based on Semivariogram in order to Tehran was evaluated in a wider zone. Interpolation pollutants, calculate land surface temperature and definition and rusty texture were investgated to detect the Tehran Geomorphic System. The results indicated to dominate physical processes in Tehran. But the involvement of pollutants, land surface temperature and comparison of field observations in the rusty and good texture shows a system of chemical Weathering in the south and center of Tehran, which is also seen scattered in the margins. Thus change of Geomorphic System exists in central and southern Tehran which is spreading around by increasing urban density and pollution.
